Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise.

NSIDC is also a CoreTrustSeal-certified Regular Member of the World Data System (WDS), signifying that NSIDC provides reliable, high-quality data services.

Ocean water drives a significant portion of ice loss for the Antarctic Ice Sheet, where surface temperatures are still too cold to influence a lot of surface melting. Thus, in contrast to Greenland, surface melting affects only a tiny proportion of the mass loss from the Antarctic Ice Sheet.

In 1982, NOAA designated data activities of the WDC for Glaciology, Boulder as the National Snow and Ice Data Center and an affiliate of other NOAA data centers.

Ice loss is speeding up Not only is Antarctic ice melting more quickly than new snow can replace it, but the rate of loss due to melting and calving is increasing. Each year, the ice sheet is shrinking more rapidly.

Running out of margin Greenland holds enough ice to raise global sea levels by 7 metres if it were all to melt. The sheet currently loses around 270 billion tonnes of ice each year, and contributes a substantial fraction of the current global sea-level rise, which is more than 4 millimetres annually.

NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) This program manages and provides open access cryosphere and related geophysical data from NASA Earth-observing satellite missions, airborne campaigns, and field observations.

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly.
